Objective To identify the chief factors influencing health insurance patients' hospitali-zation expenses so as to provide basis for the control of irrational increase in medical expenses and reform in the mode of medical insurance payment. Methods All the medical insurance cases involving the three disease entities in two hospitals of a certain city for the past three years, which totaled 647, were collected and a statistical analysis was made of the possible influencing factors using multi-stepwise regression analysis.

Reducing length of stay and lowering proportion of drug fees were the key to controlling expenses.
